What probably matters to youSection of the release
What
Claude Code no longer sends a candidate shell command to a model to work out its safe prefix before running it. That means one fewer round-trip and one fewer thing that can stall or fail before a command starts. The prefix is now derived locally from the already-parsed command.
Details
The removed results command_injection_detected and dangerous_shell_prefix no longer exist.
The 10-second message "Pre-flight check is taking longer than expected" can no longer appear.
Evidence
dangerous_shell_prefix
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
